Application filed September 18. 1909. Serial No. 518,423.

To all whom it may concern:

Be it known that I, ERNEST F. T. Luxu- UIsT, a citizen of the United States of America, and a resident of Chicago, county of Cook, State of Illinois, haveinvented c -r tain new and useful Improvements in Button-Making Machines, of which Qth'e following is a specification;

My invention relates to button-making machines, and has for its object improvements in the construction and operation of such machines.

In the accompanying drawings,-I*igure 1 is an elevation; Fig. 2 is a section on line 2-2 of Fig. 1; and Fig. 3 is a similar section, with the lower die carrier moved to a different position.

Secured to the base 10 are two upright posts 11 and 12, on the upper end of which is a head 13 vertically adjustable on the posts by nuts 14. In the center of the head 13 and midway between the posts 11 and 12 is a plunger 15, which is held in an elevated position by a spring 16 having one end hearing upon a lower portion of the head 13 and an upper portion bearing against a pin 17 i in the plunger 15.

Pivoted in the upwardly-extending lugs 18 is a hand lever 19 having a cam 20 adapted to engage the upper end of the plunger 15 and force it downward against the action of the spring 16. When the lever is elevated after such movement, the spring 16 returns the plunger 15 to its elevated position.

Secured to the lower end of the plunger 15 a die 21 which is vertically slidable upon a stem 22, which stem has a collar 23.

"lhis stem and the collar are parts of the die which is secured in the lower end of the plunger 15, the part 21 being in fact a diehead,.whichis adapted to vertically slide upon the central portion 22.

Secured on the lower end of the plunger 15 just above the die is a collar 24 held in a place by a set screw25. This collar has a projection 26 extending laterally, and from this, projection is a pin 27 extending downwardly parallel with the axis of the plunger 15 and the die 21.

"Loosely mounted upon the pin, 27 is an arm 28, which is held from dropping off by a dowel pin 29 in the lower end of the pin 27., The arm 28 extends lateral to erlgage the stem 22 between the die-head-21 and the collar 23. A. spring 30 on the pin 27 normally causes the arm 28 to engage the stem 22 so as to fill the space between the die-head 21 and the collar 20, and thus prevent the die-head from sliding on the stem 22. The spring 30 also permits a slight vertical movement of the arm 28 on the pin 27.

Iivoted upon the lower end of the post 12 is a quadrant-shaped arm 31 having a handle 32 by which it may be moved. Supported on the quadrant 31 are dies 33 and 34, which are adapted to be moved under the die 21 successively by moving the quadrant to either extreme of its movement, these extremes being determined by engagement of lugs or projections on the quadrant with a projection 35 (see Figs. 2 and 3) on the base 10. y

On one side of the quadrant 31 is an arm 36 provided withan upright pin 37,which is adapted to engage the short end of the arm 28 on thepin 27. Fig. 2 shows the pin 87 removed from arm 28 and the said arm engaging the stem 22. Fig. 3 shows the quadrant t rown around to the other position so that the pin 37 strikes the projecting end of the arm 28 and moves that arm from engagement with the stem 22, and conse uently from between the die 21 and the collar 23. When so removed, the die 21 can of course slide on the stem. By observing Fig. 3, it will be seen that the pin 37 passes a little beyond the straight line projected through the centers of the post 12 and the pin 27. The result of this action is that the spring 30 does not act to push the quadrant back away from its extreme position. In other words, the passage of the pin 37 beyond the center line between 12 and 27 forms a self-locking arrangement.

In operation, the dies 33 and 3 1 are suc- Passively moved under the die 21, and the plunger 15 is moved downward so as to force the die 21 against the horizontallymovablo dies 33 and 34. "Whenthe die 33 is beneath the die 21., the arm 28 is between the die 21 and the collar 23, with the result that the die 21 cannot slide .upon the stem 22. When, however, the die 34 is brought under the die 21, the pin 37 has pushed the arm 28 away from the stem 22, with the result that upon moving the plunger 15 downward, the die 21 will slide upward on the stem 22.

The collar and arm 28 is supported from the plunger 15 is made vertically adjustable by said screw 25 so as to accommodate dies of different lengths or dies having their collars 23 at difl'erent distances from the lower end of the' sprlng tension applied in the corresponding vertical movement of said arm 28.

In machines of this kind, where the plunger is moved one way by a cam and the other way by a spring, there is a certain amount of wear on the upper end of the plunger 15 and on the faceof the 'cam by which it is moved. In machines heretofore made there has been provided no means for taking up this Wear. In the device herein shown, this is accomplished by means of the nuts 14: adjustable on the posts 11 and 12. When there has been any considerable wear, orwear enough that requires adjustment, the

a head 13 maybe lowered to accommodate for this wear, and in this sense the head is adjustable for this purpose.

What I claim is: I 1. In a machine of the character described, a vertically reciprocating plunger and a sliding die thereon, a member for control ling the sliding action of the die, means by which said member may be adjusted, and a self locking device for holding the member from engagement with the die.

2. In a machine of the character de-' scribed, a vertically reciprocating plunger, a die secured to the end of the plunger and arranged to slide thereon, and a member for controllin theslidin action 0*? the die L: 23 z 7 sald member being secured to said plunger and being vertically adjustable with respect thereto so as to adapt it to dies of ditlerent lengths.

3. In a machine of the character de-' scribed, a vertically reciprocating plunger, a die carried by said plunger and movable thereon, an arm secured to and vertically adjustable on said plunger near said die, a pin secured to said-arm, and amember pivoted on said pin and serving to control the sliding action of said die.

4. In a iachine of the character described, a vertically reciprocating and sliding die, a spring actuated member for controlling the sliding action of thedie, means for adjusting said member with respect to said die, and self-locking means for holding the member from engagement with the die 5. In a machine of the character described, thecombination with a reciprocating plunger and a sliding die thereon, and a member for controlling the sliding action of said die, of a horizontal movable die-carrier,

and a projection on said carrier arranged to move said member from operative position, said member and said projection being so related to each other as to form a self-locking combination against self-displacement.
